When buying an air conditioner for a small bedroom, guest room or home office (100 to 250 square feet), look for an AC unit with a capacity of 5,000 Btu/hr to 6,000 Btu/hr. And when buying an air conditioner to cool a bigger or busier room such as master bedroom or playroom (300 to 400 square feet), you’ll want to step up to a mid-sized air conditioner rated at 8,000 Btu per hour.
An 8,000 Btu air conditioner usually costs less than $300, some expensive models can cost up to $800. But because you’ll have to spend 13% to 15% of annual utility bill on your air conditioner (according to Energy Star), so the price isn’t the most important thing to consider here when choosing an air conditioner.
Before you consider price, start by determining the size of unit you need for the space you want to cool. Making sure that an air conditioner with a capacity of 8,000 Btu is the right unit. An air conditioner that’s too small will struggle to cool a room. One that’s too big cools so quickly that it doesn’t have time to remove enough moisture, leaving you with a cold, clammy space. Buy just right and you’ll feel just right and save money too.
Buy an energy-efficient air conditioner provides further help in cutting down on utility costs. Look for a unit with an Energy Star label and an Energy Efficiency Ratio (EER) of 10 or above. An Energy Star qualified device uses 15% to 20% less energy than the units without that certification. And the higher the EER, the lower your operating costs.
If you want an air conditioner to use in your bedroom, look for the models which have a quiet operation, convenient controls. The best air conditioners should come with filters that are easy to clean, a dirty filter can cause some serious problems to your air conditioner efficiency. Many good models on the market have a dehumidifying function which reduces the level of humidity in the air.
Window and portable are the most common types of air conditioner rated at 8,000 Btu. Portable units are often less powerful than similarly sized window units. Portable air conditioners are also more expensive and use more energy. Portable air conditioners are intended for homes in which window configurations or building regulations prevent installation of through-the-wall units or window units.
